TREE-FELLING WINDLASS.

Specicaton of .Letters Patent.

Patented Nov. 28, 1905.

Application tiled April 11,1905. Serial No= 255,067.

To @ZZ whom t may concern:

the people employed, as well as the surrounding cultivation, are protected from damage.

This appliance consists, in the main, of a crosstree which rests against thetree to be.

felled and which is movable in its longitudinal direction by means of a toothed-bar windlass-work with wheel connecting-gear parallel to a supporting-tree, which latter transmits the pressure exercised to fell the tree to the ground by means of a movable foot-plate, as well as a suitably-anchored chain fastened to same.

In the accompanying sketch, Figure l shows the appliance in front View. Fig. 2 represents a cross -section on .line A B, Fig. .1.

Fig. 3 a section on line C D, Fig. l.- Fig. 4

shows a side view of the windlass. Fig. 5 represents a section through the windlass on line E F, Fig. 4. Fig. 6 shows a section through the windlass on line G H, Fig. 4.

The tree-felling windlass is placed against the tree in a slanting position and opposite to the direction in which the tree to be felled is to fall. It consists of a crosstree u, which on the one part grips the hewed or blazed tree c by means of a fork b and on the other part is, however, ixed in the shoe cl of the windlass-work, which rolls on a supporting-tree e. This transmits the pressure exercised by the windlass-work in such a manner to the ground that the vertical pressure is taken up by a foot-plate f and the horizontal pressure, which brings about the slipping of the supportingtree, by a suitably-anchored chain g, fastened to the foot-plate. By the working of the windlass-work the crosstree is moved in its longitudinal direction parallel to the supportingtree until the blazed tree falls to the ground by the pressure exercised.

The crosstree o, set in the shoe d of the windlass-work, slides for the purpose of better guidance and connection with the supporting-tree e on a roller r, Fig. 3, attached to its upper end, which is placed in a bow L, which latterv serves to set up the appliance.

Figs. l tot represent the'windlass-worh, which is guided by rollers fr on the supportingtree.V The same consists of atoothed-bar windlass with doublewheel connecting gear c', which is worked by means of movable cranks it.

That I claim as my invention, and desire to secure by Letters Patent, is'- In an appliance for felling trees, the combination with a toothed bar c, a windlass arrangement, which can be moved on the toothed bar, and a rod a which sits rigidly on the wind- HEINRICH BTTNER.
